Potter wasps belong to the subfamily Eumeninae of the family Vespidae. Potter wasp is a common name given for a group of caterpillar hunting wasp which builds the pot-shaped mud nests. Initially the wasp constructs the nest and then starts hunting for its prey, the caterpillars. The prey is stung and paralyzed by the wasp then brought to the nest. It is perhaps a very highly specific behavior of these wasps.
